Peripheral defocus is a hot topic in the prevention of myopia (nearsightedness) in children. Peripheral defocus comes from the concept that the entire back surface of the eye is not in focus at any one time for someone to see. Even if the central retina is in focus, the peripheral retina may be under or over corrected. Research is being conducted to see if controlling the peripheral defocus may control myopia and aid in nearsightedness control. Researchers are also trying to detect if hyperopic defocus or myopic defocus may be a marker for future development of myopia. Many studies have been designed to test if altering the peripheral defocus with different types of lenses or contact lenses may have an impact on peripheral defocus and in slowing myopic progression. Previous studies involving single vision lenses, soft contacts and RGPs have shown varied results. In 2013 a study by Berntsen found that progressive lenses caused a superior myopic shift in peripheral defocus and less central myopic progression in children. Further studies have found that soft multifocal contact lenses may also have the ability to slow myopia progression. If further research continues to show a decrease in myopia, progressive lenses, anti-fatigue lenses and soft multifocal contact lenses may be a useful tool in slowing myopia progression in at-risk children.
